Setting up a Lincoln LN 25

amateurwelder · Mar 10, 2012

I am a rank amateur, but have a "61" SA200 Redface, I set up an LN25 and I am having some trouble getting everything set. Running power for LN off positive post, setting at medium heat range (5 settings), 50 or so on the fine setting. I am using Lincoln 211 .045 fluxcore. At times I get a lot of spatter, then if I crank it up and burn it in pretty hot, not so much and a pretty nice weld. Any tips about setup, I may be all wrong, just like a little advice. Welding mostly mild steel, but will be doing some oilfield pipe and sucker rod soon. Thanks for any help.

Fluxcore? Set it up for electrode negative (straight) polarity and make sure the LN-25 is set to CC.

If you don't have a manual for the unit you can down-load it here:

Duane nailed it!
I can't help you with settings, because I can't remember from one machine to the next, but it generally only takes me a few seconds to dial a machine in. Here is Innershield run on a Red Face. 7018, and most T-11 wires run great on a Red Face.

I have been away from here for a few days, but appreciate the information. I set things up like you recommended and it worked pretty well. I did see quite a bit of difference in the quality of the weld using the fine adjustment. Thanks for the help.

Nice welds, my old redface likes 7018 and I set up for the 211 wire and it will be good when I get it dialed in right. Thanks.

Yeah, they're different to dial in than a electric powered Mig machine.
